INTELLECTUAL PROPERTY REFUSAL for a 300 years old location. Need your feedback.

All good advice that you got here. But you really need to read the links that I and others provided. They give you many clues about what to do or not to do.

You did simply blur faces and logos. That is done sometimes for editorial work, to protect the identity of peple and locations. But you don't submit for a case like this. Someone will need your picture for a commercial or similar, and they will not be amused to see your awful work. It is clearly written in the documentation that you will need to photoshop those things out, in a way that lets no hint to your work. These are technical issues.

I think, that there are also other technical issues, but I did not look at those and cannot make any assessment on this for the moment. Just that I noticed, that the shop windows were overexposed.

I do not think, that the shop windows will trigger IP concerns, if there are no logos shown and the shops are pretty common. My thoughts in this sense are the following: To trigger IP here, the shop windows (or even better one shop window) needs to be the center of interest for the viewer. Or, the center of interest lies in this nice architecture. 

What triggers IP, besides the logos is, that you are inside a gallery and moderators will assume, that someone controls access to the building, so that someone needs to give you a property release. It's completly irrelevant if there is none needed. You have to prove that you are allowed to take pictures for commercial use.

There are too many IP issues to count in this photo.  In general, someone owns the IP to anything man made and for anything recognizable you'd need explicit permission to use.  Clothing design, shop displays, the lighting, are some examples I found with a quick browse.  I suspect there are many more in this photo.

I believe blurring out the IP issues would catch a technical issue for blurriness, although I've never tried it.

In addition, there are other technical issues along with the IP issues that I think would prevent this photo from being accepted.

I wish you success!

Also, each shopkeeper has the IP rights to their shop display. You have many, and each shopkeeper could sue you. Look at everything - small details, not just the building.

Blurring out the logos is not enough. They are still identifiable. They must be removed.

Also your blurring of the peoples faces will probably not be accepted. It does not look well.

Next time, due a time lapse with a ND filterh attached.
